Re: [lustre-discuss] Configuring LustreFS Over DRBD
Hi Shambhu, I also think active-active is not possible here - two NIDs for the same target? - but we have been running our MDTs on top of DRBD, which works quite well. The last time I compared this setup against a mirror of storage targets, DRBD was actually a bit faster. And it might improve if you use protocol B or A instead of C.

Re: [lustre-discuss] Configuring LustreFS Over DRBD
Hi Shambhu- I believe neither the ldiskfs nor ZFS OSDs support an active-active configuration (except in the sense that one can have multiple targets, some of which are active on one host and others on another). It seems reasonable to me, only having used DRBD and Lustre independently of each other, that it would be possible to use DRBD in active-passive mode in place of shared storage for fail-over, but with inferior performance. Clients would connect to whichever server is currently active for a particular target. If instead what you're talking about is mounting a filesystem for simultaneous use on the DRBD hosts themselves, you're looking for a "shared-disk" clustered filesystem, not Lustre, which is a "distributed" clustered filesystem. -Laura ___ lustre-discuss mailing list lustre-discuss@lists.lustre.org http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
[lustre-discuss] Configuring LustreFS Over DRBD
I am trying to configure a clustered file system over DRBD software so that if we mount a file system just like LustreFS over DRBD set -up in dual primary mode it can provide us with the real time replication of data . Can I configure lustre file system over DRBD in redhat 8.7 ... If yes, how can it be configured ?
